EN ISO 13503-5:2006 (E)3Introduction This part of ISO 13503 is largely based on API RP 611. Informat
22、ive references are also included in the Biblography, References 2 to 15. The tests and test apparatus herein have been developed to establish standard procedures and conditions for use in evaluating the long-term conductivity of various hydraulic fracture proppant materials under laboratory conditio
23、ns. This procedure enables users to compare the conductivity characteristics under the specifically described test conditions. The test results can aid users in comparing proppant materials for use in hydraulic fracturing operations. The procedures presented in this publication are not intended to i
24、nhibit the development of new technology, materials improvements, or improved operational procedures. Qualified engineering analysis and sound judgment is required for their application to fit a specific situation. This part of ISO 13503 may be used by anyone desiring to do so. Every effort has been
25、 made by ISO and API to ensure the accuracy and reliability of the data contained in it. However, ISO and API make no representation, warranty, or guarantee in connection with this part of ISO 13503, and hereby expressly disclaim any liability or responsibility for loss or damage resulting from its
26、use or for the violation of any federal, state, or municipal regulation with which this part of ISO may conflict. In this part of ISO 13503, where practical, U.S. customary units are included in parentheses for information. EN ISO 13503-5:2006 (E)4CAUTION The testing procedures in this part of ISO 1
27、3503 are not designed to provide absolute values of proppant conductivity under downhole reservoir conditions. Long-term test data have shown that time, elevated temperatures, fracturing fluid residues, cyclic stress loading, embedment, formation fines and other factors further reduce fracture propp
28、ant pack conductivity. Also, this reference test is designed to measure only the frictional energy losses corresponding to laminar flow within a pack. It is recognized that fluid velocity within an actual fracture can be significantly higher than in these laboratory tests, and can be dominated by in
29、ertial effects. 1 Scope This part of ISO 13503 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations. NOTE The “proppants” mentioned henceforth in this part of ISO 13503 refer to sand, ceramic media, resin-coated proppants, gravel pa
30、cking media, and other materials used for hydraulic fracturing and gravel-packing operations. The objective of this part of ISO 13503 is to provide consistent methodology for testing performed on hydraulic-fracturing and/or gravel-packing proppants. It is not intended for use in obtaining absolute v
31、alues of proppant pack conductivities under downhole reservoir conditions. 2 Normative reference The following referenced document is indispensable for the application of this document.

35、ID Proportional-integral device 5 Procedures for evaluating long-term proppant pack conductivity 5.1 Objective The objective is to establish a standard test procedure, using a standard apparatus, under standard test conditions to evaluate the long-term conductivity of proppants under laboratory cond
36、itions. This procedure is used to evaluate the conductivity of proppants under laboratory conditions but is not intended for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions. The effects of fines, formation hardness, resident fluids, time, and/or o
37、ther factors are beyond the scope of this procedure. 5.2 Discussion In this part of ISO 13503 procedure, a closure stress is applied across a test unit for 50 h 2 h to allow the proppant sample bed to reach a semi-steady state condition. As the fluid is forced through the proppant bed, the proppant
38、pack width, differential pressure, temperature and flow rates are measured at each stress level. Proppant pack permeability and conductivity are calculated. Multiple flow rates are used to verify the performance of the transducers, and to determine darcy flow regime at each stress; an average of the
39、 data at these flow rates is reported. A minimum pressure drop of 0,01 kPa (0,002 0 psi) is recommended; otherwise, flow rates shall be increased. At stipulated flow rates and temperature conditions, no appreciable non-darcy flow or inertial effects are encountered. After completing the rates at a c
40、losure stress level in all cells, the closure stress is increased to a new level; 50 h 2 h is allowed for the proppant bed to reach a semi-steady state condition, and multiple flow rates in all cells are introduced to gather data required to determine proppant pack conductivity at this stress level.
41、 The procedure is repeated until all desired closure stresses and flow rates have been evaluated. To achieve accurate conductivity measurements, it is essential that single-phase flow occurs. Test condition parameters, such as test fluid, temperature, loading, sandstone and time, at each stress shal
42、l be reported along with long-term conductivity and permeability data. Other conditions can be used to evaluate different characteristics of proppants and, therefore, can be expected to produce differing results. EN ISO 13503-5:2006 (E)66 Reagents and materials 6.1 Test fluid The test fluid is 2 % b
43、y mass potassium chloride (KCl) in a deionized or distilled-water solution filtered to at least 7 m. The potassium chloride shall be at least 99,0 % by mass pure. 6.2 Sandstone Ohio sandstone cores should have dimensions of 17,70 cm to 17,78 cm (6,96 in to 7,00 in) in length, 3,71 cm to 3,81 cm (1,4
44、6 in to 1,50 in) wide, and a minimum of 0,9 cm (0,35 in) thick. The ends of the sandstone cores shall be rounded to fit into the test unit (see 7.1). Parallel thickness shall be maintained within 0,008 cm ( 0,003 in). 7 Long-term conductivity test apparatus 7.1 Test unit The test unit shall be a lin

The pistons and test chamber(s) shall be constructed of 316 stainless steel (e.g. ISO 3506-1, Grade A4), Monel1)or Hastalloy material. Filter
46、s for the test unit may be constructed using Monel wire cloth with an opening of 150 m or equivalent (100 US mesh). Nominal particle retention sizes are greater than 114 m. 7.2 Hydraulic load frame The hydraulic load frame shall have sufficient capacity to develop 667 kN (150 000 lbf). To ensure uni
47、form stress distribution, the platens shall be parallel to each other. It is recommended that the hydraulic load frame be of a four-post design that minimizes warping that can be transmitted to the test cell. Each post should have a minimum diameter of 6,35 cm (2,5 in). The hydraulic pressurization
48、source shall be capable of holding any desired closure stress 1,0 % or 345 kPa (50 psi), whichever is greater for 50 h. The hydraulic load frame shall be capable of loading rate changes of 4 448 N/min (1 000 lbf/min) or 690 kPa/min (100 psi/min) on a 64,5 cm2(10 in2) cell. A calibrated electronic lo
49、ad cell shall be used to calibrate the stress between the hydraulic ram and the opposing platen of the load frame. 7.3 Pack width measurement device(s) Pack width measurements shall be made at each end of the test unit.
